I am sorry, but I was confused. You said you would compute p-value
tests, but those are only really valuable if you have over a 90%
confidence level in the data. Using a non-random sampling polling
method which the forum comes in.. I was advised that the best
confidence level one could have was 60% with it probably being more
like 50%. At this point your +/- % is about 50% also.
At this point, what I can say about the survey is that somewhere
between 1% to 100% of people want 'adventurous updates'. And between
1% and 100% do not. Yes the number 78% looks really strong but the
confidence in it is so low that it could just as easily have been 22%
.. and just as been accurate.
